Make capact install "internetless" if needed

[mszostok]

Description

Changes proposed in this pull request:

• Add opt to use local Helm charts. Using --helm-repo you can specify relative path to current working directory or URL.

  # Install with locally pulled Helm charts, version is required
  capact install --version 0.4.0 --helm-repo charts/capact
  
  # Install with local Helm charts
  capact install --version @local

• Change tracing to trace to unify naming, --verbose=simple/trace/disable

• Change --helm-repo-url to --helm-repo as now it can be path or URL in case of install. As the upgrade is executed by Capact Action it still needs to download charts from the internet.

• Print msg Trusting self-signed CA certificate (..) only if needed.

• Change ingress folder name to match the chart name

• Update populator docker images to contain local hub-manifests fetched from git.
